Hi there!

I get the following error, when i try to initialize a connection with libjingle_peerconnection revision 16624:


02-15 12:39:09.543 1549-1549/? E/rtc: #
                                      # Fatal error in ../../webrtc/modules/utility/source/helpers_android.cc, line 68
                                      # last system error: 2
                                      # Check failed: !jni->ExceptionCheck()
                                      # Error during FindClass: org/webrtc/voiceengine/BuildInfo
                                      #
02-15 12:39:09.544 1549-1549/? A/libc: Fatal signal 6 (SIGABRT), code -6 in tid 1549 (m.vypii.android)

Everything was working fine until revision 16107, while 16232, 16404, 16567, 16603, 16611, and 16624 failed with that error message.

Any ideas?

Cheers!

Kay

Can you reproduce with same WebRTC version on any other device with a later Android version?

It is also failing on another Intel X5 based device with Android 5.1.1. I've emulated an Android 6.0 environment and it is also failing there with the same error..

Can't say why that happens and I can't reproduce. Please file a bug and explain exactly how to reproduce.

Use a default Android application (AppRTCMobile) as reference and compare.

This sounds like you need to link with audio_device_java.jar.

+mbonadei, who was working on this area. Was linking to audio_device_java.jar not necessary until recently?

Hi Taylor,

thanks for your hint, it is working now! I've included audio_device_java.jar manually.

Cheers!

Hi Pony and Taylor,

'audio_device_java' was already necessary but it was included in 'libjingle_peerconnection_java' through a workaround that was violating the package boundaries:

android_library("libjingle_peerconnection_java") {

java_files = [

# This is package boundary violation, we want to avoid this.

"//webrtc/modules/audio_device/android/java/src/org/webrtc/voiceengine/BuildInfo.java",

"//webrtc/modules/audio_device/android/java/src/org/webrtc/voiceengine/WebRtcAudioEffects.java",

"//webrtc/modules/audio_device/android/java/src/org/webrtc/voiceengine/WebRtcAudioManager.java",

"//webrtc/modules/audio_device/android/java/src/org/webrtc/voiceengine/WebRtcAudioRecord.java",

"//webrtc/modules/audio_device/android/java/src/org/webrtc/voiceengine/WebRtcAudioTrack.java",

"//webrtc/modules/audio_device/android/java/src/org/webrtc/voiceengine/WebRtcAudioUtils.java",

"api/org/webrtc/AudioSource.java",

[...]

So we refactored the target in these two commits:

- https://chromium.googlesource.com/external/webrtc/+/10a76592a78762187bfaf3547b7e9986454062ab%5E%21/#F3

- https://chromium.googlesource.com/external/webrtc/+/a62a82b7e7da5a1bbbf8b5614ef19334cc1603ce%5E%21/#F0

At the beginning we included audio_device_java through the 'srcjar' attribute but after a review we decided to avoid to rely on that feature of 'android_library' and we created a new target: '//webrtc/sdk/android:libwebrtc' which creates a jar with everything.

Pony, can you try to depend on '//webrtc/sdk/android:libwebrtc'? In this way you can avoid to declare two dependencies.

Let me know.

Hi Mirko,

do you want me to include that dependency in my build.gradle file or do i have to link to it somehow for the libjingle_peerconnection build? I am quite limited regarding the peerconnection build, as i am using Pristine's build scripts.

Cheers!

Hi,

You should modify the script to include libwebrtc.jar instead of libjingle_peerconnection_java.jar and base_java.jar.

Hi Sami,

unfortunately there is no libwebrtc.jar file. Will i have to get it from some external source?

Best regards,

Hi,

Oh, it is not built by default. You can build it by manually specifying the target i.e. "ninja -C out/Debug libwebrtc".

As always, please provide detailed information from the beginning when asking questions like this.

The fact that https://github.com/pristineio/webrtc-build-scripts was used for this build makes me think the primary forum for reporting issues with that (which is not maintained by the WebRTC team) should be filed at https://github.com/pristineio/webrtc-build-scripts/issues rather than at this list.
